Damian, Pragmatically speaking, I strongly suspect the increase in valid queries to authoritative servers even if all “large recursive resolvers” went away would be lost in noise of the overcapacity necessary to deal with even a lower-end DDoS attack. Perhaps more interestingly, if said recursive resolvers on home routers would implement DNSSEC with RFC 8198 (and the owners of the authoritative zones would sign those zones), an entire class of DDoS attack would be mitigated. Further, if said recursive resolvers also implemented RFC 7706, latency to the root would be reduced and the risk of to the network behind that recursive resolver of a DDoS against the root of the DNS would be removed.

I'm guessing it wouldn't be pretty. Damian
